Abstract

The present invention provides a method and apparatus of hydrogen production from microorganisms, wherein a bioreactor provides an environment conducive to the production of hydrogen from hydrogen producing microorganisms and restrictive to the production of methane from methanogens. The method and apparatus includes substrates contained within the bioreactor for growing biofilm thereon, wherein the substrates may be affixed or may be buoyant such that they float to a surface of organic feed material contained in the bioreactor, the biofilm providing a source of continuous hydrogen production.
